DETAILED DESCRIPTION

The present invention provides a system and method for automated search which may allow users to program their mobile devices to automatically bring up search results when a user or a user-designated entity meets a certain set of spatial, temporal, activity, or social context conditions. The invention may be carried out on one or more computers by computer-executable instructions, such as program modules, embodied in a computer-readable medium. Advantages of the present invention will become apparent from the following detailed description.

FIG. 1 illustrates an automated search system according to one embodiment of the present invention. A user's mobile device 101 may access the Internet, a proxy server or a local database 102 via an automated search query (ASQ) server 103. A user may use his mobile device 101 to store in a database 105 some search queries, one or more conditions to automatically initiate a search using a search query, or his explicit profile information. The user may also use the mobile device to edit search queries, conditions or profile information that have been either stored into the database 105 or obtained by the ASQ server 103. The mobile device 101 may be any electronic device having access to the Internet, a proxy server or a local database, e.g., a mobile phone, a smartphone, a portable computer, a portable GPS device, or a media player. The mobile device 101 may have a screen and/or a speaker for presenting search results of the automated search to its user.

A tracking server 104 may track a mobile device 101 to get the spatial (where), temporal (when), activity (what) and/or social context (who) information about the user or a user-designated entity, collectively “status information,” and store it in the database 105 as real time status information first and as historical status information later on. The user-designated entity may be a user's family, friend or contact, and may have permitted the system 100 to collect his/her status information. The status information may include other information as well. The tracking server 104 may get the user's or user-designated entity's spatial information via positioning signals either from a mobile device or from a positioning system. With the positioning signals, the tracking server 104 may also infer the user's or user-designated entity's frequency or length of stay at a location.

The tracking server 104 may track or infer social context information about a user or user-designated entity from where he is or what he is doing. In one embodiment, the tracking server 104 may infer the social context information about a user from an RF ID, which may indicate the owner of a mobile device close to the user, and may be is associated with a brief profile of the owner. In one embodiment, users may register with a social networking website which may track the users' locations, do an aggregated social context sensing and create a heat map labeling each group of users with their most common interest. The tracking server 104 may infer identities of people who are around a user from the heat map. In one embodiment, the tracking server 104 may infer the user's relevance to other users by looking at the user's address book.

The tracking server 104 may track or infer the user's or user-designated entity's activities by monitoring the his movements. When the user is moving at a certain speed or following a certain pattern, the tracking server 104 may decide that the user is dancing. When the user is moving toward a train station, the tracking server 104 may decide that the user is trying to catch a train. In one embodiment, the tracking server 104 may determine the user's activities by where the user is, e.g., whether he is at a museum, a movie theater, or a stadium. In one embodiment, the tracking server 104 may determine the user's or user-designated entity's activities by social context. For example, if the user is in a big crowd of pop-music lovers, the tracking server 104 may determine that the user is at a pop-music concert. In one embodiment, the tracking server 104 may monitor the user's movements via an accelerometer.

The status information may also include a user's or a user-designated entity's browsing activities obtained by the tracking server 104 and stored in the database 105. In one embodiment, the tracking server 104 may monitor updates on certain websites, e.g., www.facebook.com, and www.twitter.com.

The database 105 may store users' or user-designated entity's status information, as real time status information first and as historical status information later on, browsing activities, and their profiles. The status information may include explicit information (e.g., a user's location) and implicit information (e.g., how far he is from his office). A user's profile may include explicit profile information from the user himself, and/or implicit profile information obtained by the ASQ server 103 through analyzing the user's status information including browsing activities.

The ASQ server 103 may look at a user's historical status information and browsing activity information in the database 105, infer implicit profile information about the user, and use the implicit profile information to supplement the explicit profile information. For example, it may be that a user did not include Starbucks™ in his explicit profile information. In one embodiment, the ASQ server 103 may look at the user's historical status information in the database 105 and find out that the user went to Starbucks™ 15 times during the last month. The ASQ server 103 may infer that the user goes to Starbucks™ stores frequently enough to add Starbucks™ to the user's profile as implicit profile information. In one embodiment, the ASQ server 103 may store “Starbucks online coupon” as a search query, and “when the user is moving toward a Starbucks™ store” as a condition to automatically start an Internet search.

In one embodiment, the ASQ server 103 may find out from a user's historical status information in the database 105 that a user often browses the website of a fashion boutique, infer that the user is interested in the fashion boutique Mango™ and add the fashion boutique to the user's profile as implicit profile information. In one embodiment, the ASQ server 103 may store “Mango” as a search query, and “when the user is within 1 mile of a Mango™ store” as a condition to automatically initiate a search.

Similarly, the ASQ server 103 may infer implicit profile information about a user-designated entity and use it to supplement the user-designated entity's explicit profile information.

The ASQ server 103 may compare a user's real time status information and his profile in the database 105, initiate an automated search when the real time status information meets a condition in the user's profile for automatically initiating a search, and return search results to the mobile device 101. The search results may be provided by an Internet server 106 running a website. The search results may be sent to the user as, e.g., a text message, an email, or a voicemail.

Each of the ASQ server 103, the tracking server 104 and the Internet/proxy/local database server 106 may be a computer system.

FIG. 2 illustrates a flowchart of a method for conducting an automated search based on user-provided search queries according to one embodiment of the present invention. For example, a user may want to get a weather forecast before he steps out of his house and may preprogram the system 100 accordingly.

In one embodiment, at 201, the user may enter a search query, e.g., “weather, forecast, and audio.”

At 202, the user may enter the condition for initiating an automated search using the query “weather, forecast and audio.” The condition may be “when I am within 5 feet from the front door of my house,” associated with information about the position of the front door.

At 203, the tracking server 104 may track the user's location. The ASQ server 103 may configure the tracking server 104 to detect the location of the mobile device 101 at regular time intervals (e.g., every 5 seconds) and store the real time location information in the database 105. The location information may be provided, e.g., by the GPS.

At 204, the ASQ server 103 may decide whether the user's status information meets the condition for initiating an automated search, e.g., by determining whether the user is within 5 feet from his front door. If not, the process may return to 203.

If the user's status information meets the condition for initiating an automated search, at 205, the ASQ server 103 may initiate an automated search with the query “weather, forecast and audio,” receive a list of search results, and return a weather forecast to the user's mobile device 101. In one embodiment, the ASQ server 103 may keep a weather forecast website as a favorite website and automatically connect to the website.

The user may preprogram his mobile device 101 to display the weather forecast returned by the ASQ server 103 on a screen of his mobile device 101, or play the weather forecast via a speaker of his mobile device 101.

In addition to spatial information, the user may include temporal information in the search query. In one embodiment, to reduce the numbers of automated searches, the user may narrow down the condition by limiting the search to 7 am to 9 am.

FIG. 3 illustrates a flowchart of a method for conducting an automated search according to one embodiment of the present invention. A user may have signed up for the service of the automated search system 100, providing his user ID and password and his permission for the system 100 to track his status information and send him search results. The user's user ID may be, e.g., his mobile phone number.

At 301, the user may login.

At 302, the user may input a search query. The search query may include one or more keywords, or the URL of a website. For example, the user may want to get information about concerts in San Francisco, and may input the search query: San Francisco and concert.

In one embodiment, at 303, the user may set one or more conditions for the system 100 to meet for initiating an automated search. The condition may be location-based, temporal-based, event-based or activity-based. In one embodiment, the condition may be “if I am in San Francisco at 10-11 am on Fridays.”

At 304, the tracking server 104 may monitor the user's location.

At 305, the ASQ server 103 may decide whether the condition for an automated search is met. If it is Friday, between 10 and 11 am, and the user's real time status information indicates that he is in San Francisco, the ASQ server 103 may initiate an automated search, using the search query “San Francisco, and concert.”

At 306, the ASQ server 103 may rank the search results according to their relevancy to the search query using relevancy search algorithms. In one embodiment, the ASQ server 103 may also consider the user's profile when ranking the query results. For example, if the user's profile indicates that he likes classical music, the ASQ server 103 may give information about classical music concerts higher ranks so that they may be displayed earlier in the result list.

At 307, the ASQ server 103 may send the result list to the user, e.g., by displaying it on the screen of the user's mobile phone.

At 308, the user may adjust or refine the search if he likes. For example, he may add “philharmonic” to the search query.

At 309, the ASQ server 103 may search the Internet again using the adjusted search query.

At 310, the ASQ server 103 may aggregate all search results and categorize the search results for future use. In one embodiment, the ASQ server 103 may keep a list of websites of theaters which often host concerts and search these websites during future automated searches.

The tracking server 104 may continue to track the user's response to the search result, further changes to the search query, and store the information in the database 105.

In one embodiment, the search query at 302 may pertain to data that is specific or embedded to the user's mobile device such as an address book or data in a removable storage device within the mobile device. For example, the user may want to get contact information of people in his address book who is within 5 feet radius of his current location and may input the search query: Friends close by and current status.

In one embodiment, at 303, the user may set conditions to cover conditions set in the past or future. For example, the user wants to get stock information of GOOG and MSFT for 6 months after YHOO hits $10. In another example, the user may set a condition to look for 3G iPhone prices 8 months after the product is launched.

In one embodiment, at 303, the condition may be based on the status information of a user-designated entity, e.g., “if my wife is within the vicinity of Atlanta airport an hour before her scheduled flight.” If the user's wife's GPS data confirms that she is in the Atlanta airport and it is 80 minutes before her flight, the ASQ server 103 may initiate an automated search at 304, using the search query “Delta flight 47 and current day”.

FIG. 4 illustrates a flowchart of a method for compiling a user profile according to one embodiment of the present invention.

At 401, a user who has signed up with the service of the system 100 may login.

At 402, the ASQ server 103 may receive explicit profile information from a user. The profile information may include the user's preferences for activities, e.g., what he likes to do, what he hates to do, and what he is an expert at. The profile information may also include his like or dislike of particular locations, such as his gym, his favorite restaurants, shops and movie theaters, and a golf course he does not want to play again. The profile information may further include the user's schedule, e.g., catches a train between 8 to 8:30 am, works in his office between 9 am to 5 pm, and goes to the gym at 6 pm on Tuesdays and Thursdays. The user profile information may include one or more of his methods of communication, e.g., www.facebook.com, www.aim.com, and messenger.yahoo.com.

At 403, the tracking server 104 may track the user's activities including, e.g., personal activities and browsing activities, and store information about the user's activities as historical activity information in the database 106. The personal activity information may include the user's status information, and the browsing activities may include the websites the user visited, time he spent on each web page, his on-line shopping records and on-line services he registered for.

At 404, the ASQ server 103 may infer implicit profile information about the user from the historical activity information. For example, the user often may go to see movies on Saturdays, and so may search for movie schedules. In one embodiment, the ASQ server 103 may infer as implicit profile information that the user likes to see movies on Saturdays, and may add to the user's profile “movie schedule” as a search query, “Saturday, 10-11 am” as a condition to initiate an automated search, so that the user may receive a movie schedule each Saturday.

At 405, the ASQ server 103 may consolidate explicit and implicit profile information and generate a profile for the user. The profile may include time, location, activity and social information, e.g., the user's typical schedule, routine locations, most frequented locations, routine activities, contextual information about an activity, and social contacts.

At 406, the user may review and edit the profile. The user may delete or ignore some implicit profile information added to his profile by the system 100.

403-406 may repeat to keep the user's profile up to date. The user's profile may be used with the method shown in FIG. 3 or FIG. 5.

In one embodiment, the system 100 may compile a profile for a user-designated entity. At 402, the ASQ server 103 may receive explicit profile information from a user about a user-designated entity. At 403, the tracking server 104 may track status information of the user designated entity, and/or any known information on the entity from information sites such as Wikipedia etc pertaining to the entity. For example, if the user enters stock information such as Yahoo Inc stocks, the ASQ server 103 may browse sites like finance.yahoo.com or www.nasdaq.com to obtain stock information which may include stock price, earning call information etc. The ASQ server 103 may infer implicit profile information about the user-designated entity and consolidate the implicit profile information with explicit profile information about the entity.

FIG. 5 illustrates a flowchart of a method for conducting an automated search based on system-derived search queries according to one embodiment of the present invention.

At 501, a user may login. The user may have provided his user ID, password and permission for the system 100 to track his activities and send search results, but may not enter any profile information.

At 502, the tracking server 104 may track the user to obtain his status information and browsing history information, and store the information in the database 106.

At 503, the ASQ server 103 may analyze the information in the database 105 and build up a profile for the user.

At 504, the tracking server 104 may obtain the user's real time status information including explicit and implicit information. The explicit information may include, e.g., the time 5:05 pm, May 24, his location, and his movement (e.g. slowly in one direction). The implicit information may be inferred from the explicit information, e.g., he is 200 feet from a stadium.

At 505, the ASQ server 103 may use a relevancy algorithm to determine whether his real time status information is relevant to his profile.

If the user's real time status information has some relevancy to his profile, the ASQ server 103 may automatically produce some search queries and initiate one or more searches with the search queries at 506. In one embodiment, the ASQ server 103 may find out that the user has been near a stadium for about 5 minutes and is moving slowly. With a relevancy algorithm, the ASQ server 103 may find out that there is some relevancy between the user's real time status and his profile, since the user goes to the stadium frequently. The ASQ server 103 may decide that the user is waiting in a line to buy a ticket to the stadium. The ASQ server 103 may initiate an automated search, e.g., using the name of the stadium as the search query. The ASQ server 103 may find out that a basketball game will begin in about an hour, and the stadium's tickets are available online.

At 507, the ASQ server 103 may send a text message to the user, asking him whether he is interested in buying a ticket to the basketball game online.

At 508, it may be determined whether the user changed the search. If the user did not change the search query and purchased the ticket online as the ASQ server 103 suggested, the process may proceed to 510.

If the user wanted to buy a hockey game ticket instead and changed the search query, at 509, the ASQ server 103 may initiate a new search with the changed search query. The process may then proceed to 510.

At 510, the ASQ server 103 may aggregate all user responses and categorize the user responses to a system recognizable category for future use. For example, the ASQ server may add either “basketball” or “hockey” to the users profile.

FIG. 6A, 6B and 6C illustrate embodiments of different user interfaces for setting up an automated search. FIG. 6A shows an embodiment of a user interface of time based automated search. A user may input a query title (e.g., train schedule) and the start and end time he wants the automated search to be done (e.g., 8 am to 8:30 am). The user may also input a query description, e.g., the name of a train station where he usually catches a train.

FIG. 6B shows an embodiment of a user interface of location based automated search. In addition to a query title and a query description, a user may store information about a location, e.g., cross streets, street number or positioning information of the location.

FIG. 6C shows an embodiment of a user interface of activity based automated search. As shown, the user may select a category of an activity. It will be appreciated that each of the displays FIGS. 6A-6C may be available on one device, depending on the type of query a user may wish to have run automatically at a particular time. In one embodiment, depending on how the user's profile may have changed, the user's device may select among two or more of the displays shown in FIGS. 6A-6C and present a different one in accordance with changes in the user's profile.
